I tried to go based on the ones that I found to be particularly good amongst the saturated swamp of campy films that were released around this time. There's a lot of bad with the good in this era, unfortunately, so I wanted to give you a few more (obscure) titles to add to your watchlist.
Some good ones that come to mind, aside from the usual 80s choices and ones already mentioned somewhere in this thread:
Alligator (1980) - Killer animal
Dark Night of the Scarecrow (1981) - TV movie, supernatural, revenge
Just Before Dawn (1981) - Slasher, wilderness survival
A Blade in the Dark (1983) aka La casa con la scala nel buio - Foreign, Giallo
Angst (1983) - Foreign, home-invasion
Sole Survivor (1983) - Supernatural
10 to Midnight (1983) - Crime
Humongous (1982) - Slasher
The Majorettes (1986) - Slasher, action
Near Dark (1987) - Vampire, western
Dolls (1987) - Supernatural, Gothic horror
Ghost Town (1988) - Supernatural, western
Scarecrows (1988) - Slasher, action
Intruder (1989) - Slasher
Two that I want to see are Next of Kin (1982) and Endangered Species (1982). There's a lot though that I want to see, but haven't been able to find. YouTube and Amazon Prime are usually the best bet though... and keep checking and often because stuff is getting put up and taken down so often on both services.
Really wouldn't call this my favorite but it is one I really like and I haven't seen it mentioned in this thread yet. The Burning from 1981. Decent summer camp slasher movie with appearances by a young Jason Alexander and Holly Hunter.
I would say probably not...at least not of the ones you mentioned because those parts didn't really hurt their careers and there was nothing all that embarrassing about them. Johnny Depp even made a cameo in Freddy's Dead: The Final Nightmare so he must have at least some fondness for a role that gave him his start.
Now had Kevin Bacon or Johnny Depp been say the center link in a Human Centipede....then they feel some regret lol
